C Sharp Writing To A Text File - Weebly.
The following code uses the StreamWriter class to open, to write, and to close the text file. In a similar way to the StreamReader class, you can pass the path of a text file to the StreamWriter constructor to open the file automatically. The WriteLine method writes a complete line of text to the text file.
Creating Files by Using the FileInfo Class With the FileInfo class, you can create new files, access information about the files, delete, and move files. This class also provides methods for opening, reading from, and writing to a file.
Sometimes programs use random file names. If we need to write a temp file and the path is not important, use Path.GetRandomFileName.Path.GetRandomFileName. Info: We can call GetRandomFileName many times in a loop and get different results each time.
In this article, we will learn how to readfile and write to a text file in .net using C-sharp. We will use FileStream, StreamWriter and StreamReader classes. Here we will use Stream to perform read and write operation in a text file. Before learning how to read and write files, we must be know about Stream.
